Verdant Executor dye to match Nevermore
From among the colors I posess Robin, Midday, Winter Frost, Winter Breeze and Sea Frost seem the closest to the color scheme of the Spirit Raven.
I always like to pair light colors with darker ones so I like to go with a shadow- or midnight-dye to give a nice contrast. Midnight Olive and Midnight Gold come to mind considering Nevermore is made of dark wood.
Good Luck
